    Plastic valves are integral components in fluid handling systems where corrosion resistance, lightweight construction, and cost efficiency are priorities. Comprehensive testing of these valves ensures they perform reliably under pressure, temperature, and chemical exposure.
  • 2025-06-13

    Plastic pipes—whether PVC, PE, PP, or specialty polymers—are central to water distribution, sewage, chemical transport, and industrial processes. Testing machines for plastic pipes must confirm that pipes can sustain internal pressures, resist environmental stresses, and maintain dimensional tolerances.

    Plastic fittings—ranging from couplings and elbows to tees and reducers—are critical junctions in piping systems. Testing these components guarantees leak-free connections, mechanical robustness, and compliance with pressure ratings under varied environmental conditions.
  • 2025-06-12

    Plastics span a vast range of properties — from flexible films to rigid structural components. Effective material testing is crucial to verify performance attributes such as tensile strength, impact resistance, thermal behavior, and chemical compatibility before plastics enter the marketplace.

    PE-RT (Polyethylene of Raised Temperature Resistance) is a material specifically engineered to withstand higher temperatures and pressures, making it suitable for floor heating systems, hot water delivery, and high-stress industrial piping. PE-RT valve testing equipment must therefore account for both thermal expansion and internal pressure variations across prolonged usage.

    ASB (Acrylonitrile-Styrene-Butadiene) is a durable thermoplastic material often used in valves that require enhanced chemical resistance and thermal stability. Valves made from ASB are suitable for demanding environments such as water treatment plants, chemical facilities, and industrial piping systems.

    PVC (Polyvinyl Chloride) valves are commonly found in residential plumbing, agricultural irrigation, water treatment, and certain chemical processing systems. Despite being cost-effective and easy to install, PVC valves must meet strict performance and safety benchmarks, especially when exposed to pressure or chemical stress.
